EPC requirements vary by region

Quick answer

In Brussels, the EPC is mandatory and its absence can block indexation. In Wallonia, similar rules apply with label-based restrictions. In Flanders, the EPC is required and labels E and F trigger indexation limitations. Without an EPC, your right to index may be compromised.

The EPC (Energy Performance Certificate) has become a critical document for rent indexation in Belgium. Its absence or a poor rating can directly impact the landlord’s ability to index the rent.

How to obtain an EPC certificate

To obtain an EPC:

  1. Contact a certified energy auditor for your region
  2. Schedule an on-site visit (typically 1-2 hours)
  3. Receive the certificate (valid for 10 years)
  4. Register it with the regional authority

Costs range from 150 to 400 EUR depending on the property size and region.

Practical tip

Obtain your EPC before the next indexation anniversary date. Without a valid EPC, you risk losing your right to index, which over a 9-year lease can cost thousands of euros in lost rental income.

Consequences of not having an EPC

The consequences of a missing EPC extend beyond indexation:

Regional specifics

Under the Ordinance of 27 July 2017, the EPC is mandatory for all rental properties. Without it, the tenant can argue the landlord has not fulfilled their legal obligations and refuse the indexation.

Wallonia

The Decree of 15 March 2018 requires the EPC for all rentals. Labels E, F and G trigger indexation restrictions.

Flanders

The Flemish Housing Rental Decree of 9 November 2018 mandates the EPC. Labels E and F trigger reduced indexation percentages.
